Hi all,
When any user trying to access ESS/MSS on EP, They are getting the 500 Internal Error message.
following is the details of the error:
com.sap.tc.webdynpro.services.exceptions.WDRuntimeExce ption: ComponentUsage(FPMConfigurationUsage): Active component must exist when getting interface controller. (Hint: Have you forgotten to create it with createComponent()? Should the lifecycle control of the component usage be "createOnDemand"?
